weight to length with copper wire

I have a problem . My conversion consist's of varying guages of copper wire(labelled in KG's not length) to be converted to meters. For example I have a chart that states 22awg(7Bit) copper wire is as follows; Kilogram/kilometer is 3.17 as 50 kilograms = 15,773 Meters, or 10awg(104bit) copper wire is 47.49(kilogram/kilometer) where 50kg = 1,053Meters. I was wandering If you may be able to help apply this info to create a base formula or equation to apply to any quage of wire. As I said I do have a list of KG/KM. Thanx in advance Dennis

The more individual wire strands in a wire bundle, the more flexible, kink-resistant, break-resistant, and stronger the wire is. But more strands cost more.

The lowest number of strands is 7: one in the middle, 6 surrounding it.
The next level up is 19, which is another layer of 12 strands on top of the 7. After that the number varies, but 37 and 49 are common, then in the 70 to 100 range (the number is no longer exact). Even larger numbers than that are typically found only in very large wires.

For application where the wire moves, 19 is the lowest that should be used (7 should only be used in applications where the wire is placed and then doesn't move), and 49 is much better. For applications with constant repeated movement, such as assembly robots, and headphone wires, 70 to 100 is mandatory.

For applications that need even more flexibility (welding is the usual example, but also any need to move wire in tight areas), even more strands are used. One example is a 2/0 wire made from 5,292 strands of #36 gauge wire. The strands are organized by first creating a bundle of 7 strands. Then 7 of these bundles are put together into super bundles. Finally 108 super bundles are used to make the final cable. Each group of wires is wound in a helix so that when the wire is flexed, the part of a bundle that is stretched moves around the helix to a part that is compressed to allow the wire to have less stress."

British Standard Wire Gauge requires table lookup. There is no formula like AWG. Diameter is 0.1016 mm, and mass about 72.2 g/km depending on the density of the copper. This is for bare wire exclusive of any insulation
